In other casting news ...

Bold and the Beautiful star Darlene Conley died of stomach cancer on Sunday in Los Angeles.

She has starred on the show as Sally Spectra for 20 years, and was diagnosed with cancer only three months ago. Producers and writers were actually developing a storyline for her to deal with the diagnosis.

Besides The Bold and the Beautiful and three other soaps (Days of Our Lives, The Young and the Restless, and General Hospital), Conley guest-starred on several other TV shows, including The Mary Tyler Moore Show, Murder, She Wrote, Highway To Heaven, The Jeffersons, Little House on the Prairie, Scarecrow and Mrs. King, Gunsmoke, Cagney and Lacey, and Ironside. She also did the voice of Mrs. Claus in Rudolph and Frosty's Christmas in July.

Patrick Duffy, who starred in Dallas and Step by Step and was once the leg of Scuzzlebutt, is coming back to television. This time Duffy will be playing Stephen Logan on The Bold and the Beautiful. Stephen is the father of Brooke Logan, played by Katherine Kelly Lang. Part of me wants to call this a step down for Duffy, but I don't think he has people banging down his door these days, so I'll just say it's cool he's getting work. Besides, he's not a bad actor. I was always impressed by his comedic talent on Step by Step, even if the show itself was absolutely wretched.
